Add the flour, sugar, baking powder and salt to the bowl of a food processor.
Pulse the dry ingredients 4 times to fully mix the igredients.
Add the pieces of very cold butter to the dry ingredients and pulse at one-second intervals until the butter is mixed in, forming buttery pebble size pieces.
Add the egg to the mixture and pulse until the dough forms a ball on the blade of the food processor.
Turn the dough out of the food processor onto a floured surface (be careful with the blade).
Flatten the dough into a disc and wrap it with plastic wrap.
Refrigerate the pie dough for 15-20 minutes before using.
Preheat the oven to 375° F.
Roll out pie dough and place it into your pie baking pan. Place the pie pan in the refrigerator until you are ready to bake. Place the pie pan on a baking sheet to make it easier to move in and out of the oven.
Place a piece of parchment over the pie dough and add the pie weights to cover the bottom and sides of the dough.Don't overfill the pie shell. Place the pan on the center rack of the preheated oven and bake until the sides of the pie crust are just set and light brown, about 8-10 minutes.
Remove the pan from the oven and let it sit for 5 minutes with the pie weights in place. After 5 minutes, carefully lift the parchment paper with the pie weights out of the pan.
Using a fork, dock the bottom and sides of the crust to help keep the crust from puffing up.If the edges start to get too dark, cover the edges with foil or a pie shield to keep it from browning too quickly. Place the pie pan back in the oven and continue to bake for 5 minutes until the pie crust is golden brown.Check the pie crust to see if it has puffed up. If it has, use a spoon to press the bottom and sides, but be gentle. Transfer the pie crust to a cooling rack and allow it to cool completely before adding the filling.
